i 2 Claims. (Cl. 103-260) Thisinvention relates to improvements in waterwell units', and particularly to such units employing a well casinghaving a lateral `discharge outlet intermediate its height.

The primary object of this invention is to provide a device of thischaracter having a tube mounted within a well casing in a manner toprovide a novel water-discharging connection thereof at a lateral outletin the Well casing.

A'further object is to provide a device of this character with a tubularassembly supported by the well casing and including compression fittingsfor sealing engagement with the casing adjacent a lateral outlet in thecasing to directwater to said outlet.

A further object is to provide a device of this character with a tubularassembly which discharges at a lateral casing outlet and which isadaptable for use with pumps of different types, such as jet pumps andreciprocating pumps.

`Other objects will be specification.

In the drawings:

Fig. 4 is a transverse sectional view taken on line 4-4 of Fig. 3 butillustrating a multiple section ring portion thereof in top plan view;and

Fig. 5 is a fragmentary vertical sectional view of a modified wellcasing construction to accommodate a pump of the reciprocating rod type.

Referring to the drawings, and particularly to Figs. l and 2 thereof,which illustrate the application of the invention to accommodate a jettype pump, the numeral designates a well casing having a cap 11 spanningand anchored at the upper end thereof as by means of set screws 12. Thecasing 10 will be provided with the usual drive point or otherreticulated member (not shown) at its lower end and will be driven to apoint below the water t-able in a manner well understood in the art. Thecasing is provided'with a lateral outlet opening 13 therein intermediateits length and at any selected elevation, with which communicates thebore 14 of a saddle type fitting 15 within which is screw-threaded anoutlet conduit 16.

apparent from the following 'I'he fitting 15 has a circular groove 17formed in the concave face thereof which confronts the casing 10, and

said groove mounts a sealing ring 18 formed of rubber,

synthetic rubber or other suitable material, and of a thickness greaterthan the depth of the groove so that said ring is'compressed when thefitting is pressed against the wall casing around the outlet 13. Anysuitable means for mounting the saddle 15 on the casing may be employed,such asa U-bolt 19 fitting around the casing with its endspassingthrough apertures at opposite sides of the fitting and mountingnuts (not shown).

In vertically spaced relation to the opening 13, the casing is providedwith a second lateral opening 20 with which communicates the bore 21 ofa saddle fitting 22,

providing means for connection of pipe 23 leading to a source ofpressure. Fitting 22 is preferably substantially similar to the saddle15 and is provided with a grooved concave face to receive a gasket ring24 for effecting sealed engagement of the fitting 22 with the wellcasing i around the opening 20 when the fitting 22 is drawn tight,

as by means of U-bolt 25 and associated tightening nuts (not shown).

The apertures 13 and 20 may be located adjacent one n another but shouldbe spaced apart longitudinally sufiiciently to avoid undue weakening ofthe well casing and to permit access to the tightening means for therespective fittings 15 and 22. The radial orientation of the openings 13and 20 may vary and may be of any orientation found suitable orconvenient. Also, if desired, the fittings 15 and 22 may be formedintegrally, i.e., as a unit.

The cap 11 is provided with a screwthreaded bore 27 centrally thereof atwhich the upper screw-threaded end portion of conduit 28 is connected.The upper end of conduit 28 will be closed, as by a closure plug 29. Theconduit 28 extends to a level spaced below the discharge opening 13 andis externally screw-threaded at its lower end for connection thereto ofa union 30 providing means for coaxially connecting thereto a lower pipesection 31.

;The tube section 28 has a lateral opening 32 therein which issubstantially aligned with the lateral casing outlet 13. The tubeportion 28 has a plug 33 therein above the level of the opening 32,which plug may be a stufiing box, a differential cylinder, or any otherunit found suitable in some instances, such as instances where the plug29 is provided, it may be'unnecessary to provide the plug 33.

An apertured disk 35 fits snugly -around the conduit portion 28 andslidably Within the well casing, being supported on the upper end of theunion or other abutment on pipe 28 spaced below the discharge outlet 13.An annular resilient sealing member 36 having a snug fit about theconduit 28 bears upon the disk 35 and has a snug fit Within the casing10. An apertured follower disk 37 substantially similar to the disk 35bears upon the upper surface of the sealing ring 36.

A sleeve 38 fitting freely within the casing and around the conduit 28bears upon the follower ring 37 and is of a length to extend to anelevation above the level of the outlet 13. The tube or sleeve 38 has anoutlet opening 39 therein substantially at the same level as the outletopenings 13 and 32. An annular apertured disk 40 similar to the disk 35bears upon the upper end of the sleeve 38 and provides means forsupporting an annular resilient gasket ring 41 similar to the gasketring 36. A follower annular disk 42 bears upon the upper surface of thegasket ring 41. A sleeve or tube 43, substantially of the same diameterand transverse dimensions as the sleeve 38, bears upon the follower ring43 and extends to a point adjacent the bottom surface of the cap 11. Anannular rigid disk 44 bears upon the upper end of the sleeve 43. Aplurality of set screws 45 are screwthreaded in the cap 11 and bearagainst the annular member 44.

ilt will be apparent that tightening of the set screws 45 will introducea downward pressure upon the assembly 35-44 which will serve to squeezeor vertically compress the ygasket rings 36 land 41 in `a manner toeffect sealing engagement thereof with the well casing 10 and theconduit 28 in a continuous circumferential manner. Consequently, waterwhich is discharged from the conduit 28 at Patented VOct. 4, 1960 itsoutlet l32 will be prevented from draining through the well casingaround the conduit 28, 31, and, instead, will be confined for dischargeat the lateral outlet 13 and the discharge conduit 16.

The lower end of the conduit 31 is internally screwthreaded to receivetherein an orifice member or litting 50 having an upwardly aring passage51 therethrough. A second tting 52, in the nature of a jet member ornozzle, is screw-threaded within the tube 31 in adjacent but spacedrelation -to the lower end of the itting 50. The jet member 52.preferably includes a nozzle portion 53 lraving Ia bore from whichextend one or more lateral passages 54 for communication with lateralapertures 55 in the pipe 31 communicating with the space within thecasing surrounding the conduit 31. The jet is constructed to permit ilowof water therearound in the pipe 31 to enter the iitting 50.

The lower portion of the pipe 31 below the level of the lateral openings55 carries -a packer mem-ber of well known construction. This packer mayinclude a lower plate 56 iixedly eanchored to the tube in any suitablemanner, a pump leather or cup member 57 defini-ng a seal and 1an upperdisk 58 titting within the cup-shaped pump leather. The packer assembly56, 57, 58 eiiectively seals the chamber thereabo've from the spacewithin the casing located therebelow.

The lower end of the pipe 31 mounts a check valve which may be of ianysuitable construction. The construction here shown entails the use of acap 60 screwthreaded on the pipe 31 and provided with a plurality ofapertures 61 spaced from a central yaperture within which is slidableendwise the stem 62 of a member having an enlarged head 63. A sealingdisk or valve member 64 is carried by the stem 62 and preferablyincludes -a rigid backing plate and a resilient or rubber face portionadapted to bear against the apertured wall of the cap 60. The lower endof the stem 62carries la head 65 which supports a plate or disk 66 uponwhich bears a coil spring 67 whose upper en-d bears against the lowersurface of the cap 60.

The construction makes possible the provision of an effectivelyoperating jet pump having a single pipe. Also, the construction has theadvantage of accommodating preassembly of the pump sections with minimumneed for parts of special dimensions or proportions, while accommodatinga wide range of locations of the lateral openings 13 and 20 in the wellcasing. Thus it is possible to accommodate any desired location of theopening 13 relative to the upper end of the well casing by merelyselecting a tube 43 of a length related to the spacing of the opening 13from the end of the wel-l casing.

=In the assembly of the pump, assuming that the well casing has beensunk so that its drive point is below the water table, the `irstoperation will be to form the openings 13 and 20 in the well casing atthe desired locations for the particular installation. The fittings 15and 22 are then connected to the well casing, and the conduits 16 and 23are connected to the llittings. Thereupon the internal structure of thedevice having been preassembled with the sleeve 43 of desired length,and having been connected to the cap 11, is lowered into the well casinguntil the cap 11 seats upon the upper end of the Well casing. The cap 11is then anchored upon the well casing by tightening the set screw 12,and the set screws 45 are operated to eliect vertical compression yandhorizontal expansion of the gaskets 36 and 41 until each of thesegaskets effects a firm, continuous, inner and outer peripheral sealingengagement with the inner conduit 28 and the casing 10, respectively.Thereupon, the well is in condition for operation.

When the pump requires repair or replacement of parts, all that isrequired to be done is to release the set screws 45 and 12 and pullupwardly on the cap 111 which oarries with it all of the internaloperating parts of the pump and thus exposes them to the workman forrepair and attention.

While this construction is'shown in connection with a pump of the jettype, it may also be used with a reciprocating type pump, if desired, byreplacing plug 33 with a pump rod packing and applying a drain betweenthe upper part of casing 10 and the lower part as shown in Fig. 3.

The construction illustrated in Figs. 3 and 4 is designed particularlyfor a pump of the reciprocating type and entails the use of aconventional well casing 100 having a drive point (not shown) at itslower end and mounting a cap 101 iat its upper tend to be anchored as bymeans of set screws 102. The well casing 100 has an outlet opening 105spaced below its upper end and communicating with the passage 106 in afitting 107, such yas a saddle, to which :a discharge conduit 108 isconnected. The concave face of the saddle has a groove `adapted toreceive a gasket ring 109 thicker than the depth of the groove andextending around the mouth of the passage 106 for engagement with thecasing 100 around the outlet 105 when the saddle is drawn tight againstthe casing, as by means of a U-bolt 2110 and means (not shown) such asnuts for drawing the U-bolt and the fitting into tight gripping relationto the casing `100.

The well casing is provided with a plurality of apertures 111 in acircular series spaced below the level of' the outlet to receiveinwardly projecting lugs 112 formed on individual sections 113 of amultiple section ring encircling the well casing and secured together bysuitable means, as by bolts 114 and nuts 115. Gaskets 116 bear uponlands 116a at the inner surface of each ring section surrounding thelugs 112 to engage the casing and effect a seal around each casingopening. The lugs 112 provide means to support an annular rigid disk 117t-ting freely within the Well casing and around a lower pipe portion 118whose upper end is threaded in the bore of a tube or sleeve 119. Anannular gasket 120 is interposed between the annular plate 117 Iand thetubular member 119 and is adapted to have a snug sealing lit within thewell casing 100 and around the pipe 11S.

r[The upper end of the sleeve 119 supports a second gasket ring 121substantially similar to the ring 120 and adapted for sealing peripheralengagement with the casing 100 above the discharge opening 105 andaround a depending tubular projection 122 of reduced dimension to titfreely in sleeve 119. Projection 122 forms a part of a sleeve orcup-shaped member 123 having a shoulder 124 bearing upon the uppersurface of the gasket 121. A tube or spacer 125 is screw-threaded in theupper end of the member 123 tot extend adjacent to the cap 101 and to bepressed upon by a rigid annular disk 126. Set screws 127 arescrew-threaded in the cap 101 to bear upon the disk 126 and pressdownwardly on the structure consisting orf parts I125, 123, 121, 119 and120 to compress the two kgaskets 120 and 121 into firm continuousperipheral sealing engagement with the well casing and with the innermembers 122 and 118 which the respective gaskets 121 .and 120 encircle.This provides a iirm sealing engagement with the well casing above andbelow the `opening 105. An opening 128 is provided in the member 119 atsubstantially the level of the outlet 105 to establish communicationbetween the interior of the parts 118 yand 119 with the outlet 105, and-a check Valve 129 is preferably mounted in said opening 128.

The pump rod 130 is reciprocable in a central opening in the cap 100 andpasses through apertures in the parts 126 and 122 and downwardly in thepumpl tube to carry the usual pump leather (not shown) in the lower endof the well below water lev-el therein in a manner understood :in theart. A suitable packing extends around the rod 130 in the member 123,the same preferably being supported upon a plate 131 bearing upon ashoulder at the lower end of cup-shaped member 123 and serving in turnAto support packing rings 132 which are pressed upon at their upper endsby an annular plate 13.3 which is depressed by threaded adjustment ofthe lower end of the screw-threaded tubular part 125 within the member123 to compress the packing 132.

The tube 12S preferably has a lateral opening 135 therein above thelevel of the member 123 and adjacent the upper end of a drainage conduit136 which communicates with a lateral passage 137 in the Well casing 100above the upper seal 121. A saddle fitting 138 carrying an annularysealing ring 139 in -its inner face and drawn taut around the wellcas-ing by a U-bolt 141i and associated nuts (not shown) provides asealed connection between the upper end of the conduit `136 and theaperture 137. The lower end of the conduit 136 communicates with thelateral aperture 141 in the Well casing below the `level of the lowergasket 120 and a sealed connection is effected by means of a lowersaddle 142 having an annular sealing gasket ring 143 in its innersurface land drawn taut by U-bolt 144 and associated nuts similarly tothe matter in which the upper saddle 138 is tightened.

It will be understood that the pipe 118 may either extend to the lowerend of the well casing or, as here shown, may be connected by a union146 with a lower axially align-ed conduit 147 extending to the lower endof the well and providing the cylinder within which the pump leatherreciprocates.

Substantially the same advantages are possessed by this construction toaccommodate a reciprocating pump as are possessed by the jet type ofpump previously described. Thus the location or elevation of the outlet-105 is readily .accommodated in each installation by the simpleexpedient of controlling the length of the sleeve 125,

and the seals are readily manipulated by operating set screws 127. Theprovision of openings 111in preselected relation to and below theopening -105 is, of course, essential in order to receive the projectingabutments 112 of the sectional ring 113. Likewise, it is necessary toprovide the apertures 137 and 141 and their associated saddle iittings138 and 142'to mount the leakage by-pass conduit. This leakage bypassconduit is not essential but is preferred by reason of the fact thatsome clearance between the cap 1411 and the pump rod 130 necessary topermit free reciprocation of the pump rod, and this clearance may beadequate to result in leakage into the interior of the casing which canbe drained by the bypass 136. It will also =be apparent that the sameaccessibility for repair and replacement of parts by the unitaryhandling of all of the structure associated with the cap 101 andconsisting of the entire internal structure of the pump is made possibleby this construction.

The construction shown in Figs. 3 and 4 requires the well casing to beof a diameter of five inches or more.

Such casings are costly for deep wells. In order to accommodate theapplication of the principle to a small diameter well casing, anarrangement may be employed of the type shown in Fig. 5. In thisconstruction, a small diameter well casing 15G may mount an enlargedupper casing section 151 within which the lateral outlet 152 is for-med.The shoulder 154 of the enlargement provides an abutment for a sleeve155 upon which bears the lower compression seal of the same constructiondescribed above and herein identified by the same reference numeralsused in Figs. l and 2.

While the preferred embodiments of the invention have beenillustratedand described, it will be understood that `changes in the constructionmay be made within the scope of the appended claims without departinglfrom the spirit of the invention.
